I checked there for stacked URs and there aren't any underneath. I hadn't noticed the day difference between LMUR and URO, that might be the issue as I have noticed the issues tends to occur with URs near end of time limit I select.

I tend to scan my region first for URs with comments by me with no comments less than 32 days old, LMUR didn't show these two (which have comments from me) when I did that. When I then scanned again for URs that are over 256 days old with no comments less than 32 days old, they show (sometimes).
